It can now fulfill the need of a reference textbook in alternate iron making area for undergraduate and post graduate students in Metallurgical, Production, Manufacturing, Chemical, Materials and to a minor extent Mechanical Engineering disciplines. The aim of fulfilling the needs of entrepreneurs and plant operators has not only been retained; it has been elaborated. Further, the basic aspects have been presented in a way that is lucid and simple to understand and should serve as an incentive to the operators and entrepreneurs to develop a deeper understanding of the process. The project engineering section now gives guidelines sufficient to make a project report. Opportunities available to this process and the competition it faces has also been highlighted. A chapter on reaction kinetics has been included as also a section on iron ore and pellets. Other sections included are on Aerodynamics, Auto Ignition, Coal Throwing, etc. Rest of the text has been updated to the extent possible. Some advanced features have been introduced such as Mathematical Modeling, Computational Fluid Dynamics, Reduction Mechanism, etc. to give researchers in the area of food for thought.
